' 7 C1sims.` (C1. 10s- 7) This invention relates generally to aprotective covering and moreparticularly to an interlocking type ofshingle.

One of the difficulties hitherto experienced in shingles of thischaracter has been the fact that it has been dicult to fasten theshingles to the roof and it is a primary object of the present inventionto overcome this diiculty by providing novel means for interlocking theshingles t0- gether and also fastening the shingles to the roof.

Other objects, advantageous and meritorious qualities reside in thespecial construction, combination and arrangement of the shingles, asmore fully hereinafter described and claimed, reference to be had to theaccompanying drawing, forming part hereof, wherein:

Fig. 1 is a plan View of a roof or the like having shingles formed inaccordance with my invention laid thereon.

Fig. 2 is a perspective view showing the locking between the shingles.

Fig. 3 illustrates the construction of a single shingle.

Similar numerals refer to throughout the several views.

Referring to the drawing, particularly Fig. 3, l0 designates arectangularly shaped shingle, preferably formed of asbestos compositionor the like, this shingle having diagonal slits 11 eX- tendingdownwardly and inwardly from either side of near the bottom of theshingle and terminating in small circular holes 12 whereby flaps or tabs13 are formed.

Slightly below the center portion of the shingle L-shaped slits 15 arecut in the shingle and terminate in holes 16. It will be noted that thedistance 17, that is, the distance of the vertical portion of the slitl5, is less than the distance 18 which is the distance between thetermination of the lower slit 11 and the bottom of the shingle, whereby,when the shingles are interlocked, the corner portions 19 will extendover the naps or tabs 13 and hence tend to prevent their upward movementby stifiening them. This is clearly illustrated in Fig. 2 of thedrawing.

Referring to Figs. 1 and 2, the manner of laying the shingles will beapparent. The shingles are laid in the usual manner by starting at thebottom of the roof and proceeding upwardly. As each single is laid, itsbottom edge 21, see Fig. 2, is slid into the L-shaped slit 15, themiddle portion of the shingle extending over the upper side of theportion 22 formed by said slit 15. As previously pointed out, thiscauses the portion 19 similar parts above the slit 15 to extenddownwardly over the bottom portion of the shingle 10 which is beingplaced upon thereof and thus the lower edge 21 thereof is held tightlyagainst the shingles underneath. The flaps or tabs 13 extend underadjacent shingles, see Figs. l and 2, hence maintaining the bottom edgein taut relationship and also prevent leakage from occurring through thejoint. The bottom edge 21 of the shingle 10 rests in the holes 16 andthus prevents any tearing of the shingle 10 from occurring.

The shingle 10 which is being laid, as just recited, has flaps 13extending underneath the shingle at the side thereof and nails 23 passthrough these shingles and hold them attached to the roof.

The nails 23 which serve the aforesaid function are shown in the upperpart of Fig. 2, these nails being omitted from the locking joints shownat the bottom portion thereof for the sake of clearness. It is to benoted, however, that these nails are driven through the portions 22 asthe shingles are applied, there being two nails to each shingle, and thenails passing through two thicknesses of shingle whereby four nailscooperate with the shingle to hold it attached to the roof.

From the above description it will be appreciated that I haveinventively created a shingle which is readily formed from a rectangularpiece of asbestos sheeting or the like, such being economical asobviously there is no waste when such a shingle is cut from a roll ofmaterial. Furthermore, my shingles are easily and quickly laid upon aroof as there are only two nails driven through each shingle and theinterlocking attachment between the several shingles are readily laid,the shingle which is being laid being slid downwardly into place andthen fastened by nailing to the portion 22 as previously described.

The invention is defined in the appended claims and is to be consideredcomprehensive of all forms of structure coming within their scope.

I claim:

1. 1n combination, a roofing shingle, adapted to be laid with others inoverlapping interlocking interlocking engagement, being of rectangularform, having a slit cut inwardly from each vertical edge at an angle ina downward direction thereby forming tabs at each lower corner, and a 1horizontal slit cut inward a short distance from each vertical edgemidway between the top and bottom longitudinal edges at the terminationof each of said slits a vertical slit is cut, thereby forming a tabalong each vertical edge, said first mentioned tab in a shingleoverlapping and interlocking Awith said second mentioned tab in anadjacent shingle in an assemblage.

2. In combination, a shingle, said shingle having slits out in oppositesides thereof near one end ofthe shingle, said slits' extending towardsone end'of the shingle, said shingle also having slits extendinginwardly from the sides in which the rst mentioned slits are formedbetween the rst mentioned slits in theopposite end of the shingle, saidsecond mentioned slits having a portion thereof extending in parallelismwith the rst mentioned sides.

3. In combination, a shingle consisting of a at sheet of material ofsubstantially rectangu-y lar shape, said piece of material havingdiagonal slits extending from opposite sides thereof towards one endthereof, and L-shaped slits extending inwardly and downwardly from. thesaid sides.

4. A rooting shingle consisting of a rectangular shaped piece ofmaterial, said piece of material having diagonalslits extending inwardlyfrom opposite sides thereof towards oneend of the piece of material, andL-shaped slits extending inwardly and downwardly from the said'sdes ofthe piece of material,` all of said slits terminating in small circularopenings for the purposes described.

5. A covering for a roof consisting of a plurality of shinglesinterlocked together, each of said shingles consisting of a rectangularshaped piece of material having diagonal slits extending from oppositesides of said material near one end thereof, slits extending inwardlyfrom the said sides of the material and then extending in parallelismtoward the first mentioned slits, the length of said slits which are inparallelism with the sides of the material being of a lesser distancethan the distance between the termination of the first mentioned slitsand the end of the shingle.

6. A combination of elements as set forth in claim 5 in which thediagonal slits are adapted to be cooperatively associated with thesecond mentioned slits of adjacent shingles for the purposes described.'y

7. A combination of elements as set forth in claim 5 in which thediagonal slitsare adapted to straddle the edges of adjacent shingles ofthe second mentioned slits in saidadjacent shingles.
